| 摘要 |
The invention relates to the field of electromechanics and can be used in vibration, and vibration-and-impact devices for obtaining mechanical vibrations used in different vibration techniques, for example, for application of images on hard surfaces by targeted program-controlled fracture of surface. An exciter of mechanical vibrations is made in the form of a stepping motor equipped with springs that are connected to the shaft of stepping motor with possibility of limitation of rotation of the shaft and its return after each control signal entering to the phase windings of stepping motor. |
